Jigsaw Puzzle on Laser CutterJune 6, 2011AtI have access to a 60 Watt laser cutter. As a gift to my son I wanted to make ajigsaw puzzle of a picture of him. I printed out the picture on a colorlaser printer:I used a spray adhesiveto glue it to a piece of 8'×11'hardboard I got at Home Depot.
For the puzzle shapes I wrote a Python programthat generates an SVG file, which can be imported into Corel Draw and positionedand scaled properly. The file looks like this:The interesting part of the program was the shape of the knob. I ended upusing three circle arcs:The radius of the smaller circle is computed randomly.The radius of the larger one is 80% bigger than that of the smaller ones.We then need to compute the position of the larger circle and the angleswhere the circles should start and stop being drawn. There’s a righttriangle we can use to compute all that:Note that the hypotenuse goes through the transitionpoint between the circle arcs. The base of the triangle is half the distance betweenthe small circles (which we also choose randomly within a nice range).The hypotenuse is the sum of the small and large radii. The height youcompute using the Pythagorean Theorem, and that plus the small radius getsyou the position of the large circle.The start and stop angles of the arcs you can get using trigonometryand the lengths of the sides of the triangle. For example, the top angleof the triangle is the arc-sine of the base dividedby the hypotenuse.
See the code for details of how these values are used.A nice enhancement would be to randomize the widths of the rows andcolumns. In fact the lines themselves should not necessarily be perfectlyvertical or horizontal. These kinds of variations make it easier to solvethe puzzle—the pieces don’t all look the same, and it’s moreobvious when you’ve mismatched two pieces.Here’s what the finished pieces look like:Update 9/5/2013: Tony Schick wanted to make alarge version of this puzzle. I modified theprogram to generate 80 SVG files, one for each piece. He cut themout individually on a laser cutter and assembled the whole thing ona large plan printer at the University of South Australia. He used thisawesome photo of his grandson:The source code is.

Jigsaw Puzzle Creator is an add-on for CorelDRAW 11/12/X3/X4 and Corel DESIGNER 10/12 which allows you to create jigsaw puzzle shapes out of any CorelDRAW/Corel DESIGNER object or objects. Just import a photo, or create several shapes, select them and run the program. You will be able to create professionally-looking jigsaw puzzle which uses the selected objects as the backdrop of the puzzle.FeaturesJigsaw Puzzle Creator can create a set of closed curves looking like a jigsaw puzzle and place the selected object(s) in each of the puzzle piece so they can be shuffled on the screen to create interesting artistic designs.It also can be used to generate the knife Profiles to Manufacture jigsaw puzzles. In this case, a set of open curves is created which can be used to etch or produce the knives any other way required.
Or you can use a plotter/cutter to cut your puzzle out of acceptable media.Just start off with importing a photo or a clipart image into your CorelDRAW documentWith the object(s) selected, launch Jigsaw Puzzle Creator and you will be presented with the following dialog where you can customize the look of your puzzle.
